Original Abstract Submitted
An image sensor includes a pixel array in which a plurality of pixels are arranged, wherein each of the pixels includes a photodiode, a transfer transistor, first to third floating diffusion nodes, a first capacitor, a second capacitor, a third capacitor, a first switch transistor, a second switch transistor, and a reset transistor. The second switch transistor is configured to turn off in a first period and to turn on in a second period of an exposure period of the photodiode, and the reset transistor is configured to turn on in the first period and to turn off in the second period of the exposure period of the photodiode.
